Abstract

Extant amphibians are divided into three distinct lineages: Gymnophiona, Urodela, and Anura. Owing to their diversity, they are widely used in research concerning, among others, tissue regeneration. Here, we describe larval myotomal myogenesis in the Chinese fire-bellied newt, Hypselotriton orientalis. Morphological, ultrastructural, cytochemical, and immunohistochemical analyses showed that trunk muscles grow through hypertrophy and hyperplasia mediated by the expression of typical myogenic factors, such as Pax7, from muscle progenitor cells. Our findings also suggest a third alternative mechanism for muscle growth involving the muscle splitting or fragmentation of preexisting larval myotubes.

期刊介绍： Protoplasma publishes original papers, short communications and review articles which are of interest to cell biology in all its scientific and applied aspects. We seek contributions dealing with plants and animals but also prokaryotes, protists and fungi, from the following fields: cell biology of both single and multicellular organisms molecular cytology the cell cycle membrane biology including biogenesis, dynamics, energetics and electrophysiology inter- and intracellular transport the cytoskeleton organelles experimental and quantitative ultrastructure cyto- and histochemistry Further, conceptual contributions such as new models or discoveries at the cutting edge of cell biology research will be published under the headings "New Ideas in Cell Biology".
